The world is increasingly relying on clean energy. As a member of clean energy, hydrogen fuel has an important position in the future.

　　US president Joe Biden asked for a research project to produce a clean natural gas that is cheap enough to provide fuel for power plants within ten years.

　　Similarly, Japan, South Korea, Australia, New Zealand, and the European Union have all released hydrogen road maps, relying on it to reduce greenhouse gas emissions in the power, transportation, or industrial sectors. At the same time, more and more companies around the world are building larger and larger green hydrogen power plants, or exploring their potential in producing steel, aviation fuel or providing backup power for server clusters.

　　The grand vision of the hydrogen economy has been hindered due to the high cost of its clean manufacturing process and the large-scale investment required to build the corresponding vehicles, machinery and pipelines. In particular, competitors such as lithium batteries have made faster progress in energy storage alternatives.

　　So, what makes people rekindle their interest in hydrogen energy?

　　On the one hand, its economy is changing rapidly. The process of producing hydrogen consumes a lot of electricity. With the rapid development of solar, wind, and nuclear energy, the cost of electricity is rapidly falling, making this solution feasible.

　　At the same time, more and more countries have made difficult calculations on how to achieve their aggressive emission targets in the coming decades, and the role of hydrogen seems to be increasingly important.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Hydrogen energy system combined with lithium battery energy storage system is a very promising clean energy.
